Adjustable mounting for marking and display panel

ABSTRACT

A marking and display panel is held in upright supporting standards by a pair of panel swivel-mounting brackets which permit free rotation of the panel in its supporting standards and also the elevational adjustment of the panel along the height of the supporting standards. The panel swivel-mount brackets comprise a section fixed to the panel for rotation therewith and a fixed section adapted to slide along spaced upright supporting standards. A latch carried by the panel swivel-mount brackets cooperates with means on the supporting standards to hold the panel at a selected elevation while a position-securing screw interengaging the bracket sections secures the selected rotational position of the panel.

Dunham ABSTRACT: A marking and display panel is held in upright supporting standards by a pair of panel swivel-mounting brackets which permit free rotation of the panel in its supporting standards and also the elevational adjustment of the panel along the height of the supporting standards. The panel swivelmount brackets comprise a section fixed to the panel for rotation therewith and a fixed section adapted to slide along spaced upright supporting standards.

PATENTEU UBT SIB?! SHEET 1 BF 2 INVENTORS FOL 4ND M, HOLMES BY /s 0. PAGE v4 TOP/(15y ADJUSTABLE MOUNTING FOR MARKING AND DISPLAY PANEL It is the primary object of the invention to mount a marking and display panel in upright supporting standards in a manner that will allow both the rotational and elevational adjustment of the panel within the standards.

To the end that the primary object of the invention may be attained. there is provided herein a novel panel swivel bracket which is slidably and adjustably mounted on spaced upright supporting standards and also provides structures which permit the panel to rotate within its supporting standards.

The detailed structure and the full advantages of the invention will become apparent as a reading of the following specification proceeds in light of the drawings. In the drawings, like reference numerals indicate like parts, and:

FIG. 1 is a fragmentary perspective view of a marking and display panel mounted on the space upright supporting standards;

FIG. 2 is a sectional view on line 2-2 of FIG. 1;

FIG. 3 is a sectional view on line 33 of FIG. 1; and

FIG. 4 is a detailed view looking into the fixed section ofa swivel mount bracket along line 4-4 of FIG. 3. showing the relationship of a latch member and a height'adjusting pin.

By reference to FIG. 1. it can be seen that a marking and display panel is mounted on the spaced up right supporting standards 12 and 14 which form part of the supporting structure for the panel. These standards extend upwardly in parallel relation to each other from a general supporting base which may be conventional and is, therefore. not shown. The marking and display panel [I] may assume a variety of forms. For example, it may be a blackboard or some other panel capable of receiving written intelligence. A panel of this kind is shown in Ronald M. Holmes et al. application for US. Pat, Ser. No. 678,718, filed Oct. 27, I967, for Laminated Marking and Display structure, now abandoned. In any event, the marking panel will have a writing surface 16 on one or both sides. Alternatively, one or both sides of the panel may be of magnetic structure capable of holding symbols or objects attracted thereto. Whatever the nature of the panel 10, it is preferable to provide it with an edge bead 18 in order to maintain its integrity.

The panel 10 is held within its supporting standards by means of a pair of panel swivel-mount brackets 20 and 22. These brackets comprise a rotating section 24 and a fixed section 26. The construction of these sections is best shown in H0. 2. Each section includes disklike flanges 28 and 30 which provide a pair of confronting bearing faces 32 and 34. The rotating section 24 of the swivel brackets has an inwardly extending radial bifurcation 36 which is adapted to engage the edge of the marking and display panel [I] where it is held in position by one or more screws 38. The fixed sections 26 of the brackets have outwardly extending portions 40 and 42 which are adapted to embrace the upright supporting standards, as in the case of the standard 12 in FIG. 2. The outwardly extending portions 40 and 42 of the fixed sections of the panel swivel brackets form a seat 44 for a latch member 46, the latch member being mounted for rocking movement about a latch pivot pin 48 which passes through the latch about midway along the length of the latter. The latch member 46 has a latch handle 50 and a latch finger 52 at the opposite ends of its pivot point.

Each of the upright supporting standards 12 and 14 has means for holding the panel in a selected elevation. A suitable means is illustrated as consisting of a plurality of height-adjusting pins 54 extending from the outer face of the supporting standards. These pins are adapted to be engaged by the latch finger 52 when the latter is swung inwardly upon a selected adjustment of the marking and display panel along the length of the supporting standards 12 and 14. The height-adjusting pins 54 are in the nature of machine screws having enlarged heads 56, thus insuring substantial engagement with a semicircular recess 58in the end of the latch finger 52.

The rotating section 24 and the fixed section 26 of the panel swivel brackets are adapted for relative rotation about a pivot bushing 60 which is connected to the rotating section of the swivel brackets by means of a bushing screw 62. The rotating sections of the swivel brackets are held in fixed relation to the fixed sections 26 of the brackets by means of a hand screw 64 which is threadedly engaged with the fixed section 26 and extends therethrough. The inner end of the hand screw 64 is adapted to seat in a selected one of screw sockets 66 which are formed about the bearing face 34 of the fixed bracket section 26. Thus, the angular or rotational position of the marking and display panel 10 can be easily adjusted by backing off the hand screws 64, rotating the panel to a selected position and reengaging the ends of the hand screws 64 with appropriate screw socket 66.

The latch handle 50 of each of the latch members 46 is sufficiently heavier than the latch fingers thereof to cause a natural outward bias of the latch handle about its related latch pivot pin 48. Therefore, upward adjustment of the panel 10 along the supporting standards l2 and 14 simply requires that the panel be moved upwardly. During such movement, the latch fingers 52 will ride over the height adjusting pins 54 but upon release of the panel, the latch fingers 52 will rotate inwardly and engage the height-adjusting pins 52 immediately thereunder. and thereby secure the panel in a desired adjusted position.

It can be seen from the foregoing that there has been provided herein a novel panel swivel bracket which is slidably and adjustably mounted on its spaced upright supporting stan dards, and also that the brackets provide simple and positivi structures which permit the panel to rotate within its support-- ing standards.

While the invention has been illustrated in a single embodiment, it is believed that the disclosure thereof will permit those skilled in the art to make various changes without departing from the spirit of the invention and such modifications are contemplated herein.
